<p>在这个过程中突然发现我手里还有一个域名备案过的，一直没有用，所以就直接解析到我目前的小网站上了，新的域名备案完成，也会解析过来的。</p>
<p>Let’s Encrypt 于2018年3月14日在其官网发布了一篇<a href="https://community.letsencrypt.org/t/acme-v2-and-wildcard-certificate-support-is-live/55579" target="_blank" rel="external">《ACME v2 and Wildcard Certificate Support is Live》</a>的文章，也就预示着免费的泛域名证书正式来袭，泛域名会给你节省多少钱呢？对比腾讯卖的最贵的是一年4万。</p>

<h2 id="复制-自动续签证书"><a href="#复制-自动续签证书" class="headerlink" title="复制/自动续签证书"></a>复制/自动续签证书</h2><p>因为Encrypt的SSL证书免费，所以有效期只有3个月，那么就需要自动续签，除非你没事3个月上来执行一下命令。根据官方介绍，想用证书的时候不要自动去复制。你安装完后再<code>crontab -l</code>你会发现一个自动续签的定时命令，没有测试哦。感兴趣自己测试或者搜一下就好</p>
